The Open Lighting Architecture (OLA) provides a plugin framework for 
distributing DMX512 control signals on Mac and Linux. It provides C++ 
and Python libraries which abstract away the underlying DMX over IP 
protocol or DMX interface. See http://opendmx.net/index.php/OLA for 
more information. 

This requires protobuf and cppunit.

The build script can optionally disable python bindings and/or enable the 
embedded http server.  WITH_PYTHON=no will disable the python bindings,
and WITH_HTTP=yes will enable the embedded http server (in which case
libmicrohttp also be required).
